An autopsy is underway on the victim, who has not been identified, and three of the seven hospitalized utility workers remain hospitalized, one in critical but stable condition, Mayor Bert Steinmann said at a town hall news conference this morning.

The investigation into the cause of the explosion is continuing, Steinmann said. PSE&G
had hired contractor Henkels & McCoy to repair an electrical problem, Steinmann said, and workers were performing vertical drilling when the explosion occurred. The area had been properly marked, and the workers were following protocol, Steinmann said.

“We don’t know the ignition point,” he said. The U.S. Occupational Safety and Health Administration is participating in the investigation, he noted.

Ewing Police Lt. Ron Lunetta said the Mercer County Prosecutor’s Office began an investigation and will determine if any criminal charges will be filed.

“It’s never ruled out until the conclusion of the investigation,” Lunetta said.

Steinmann said officials will escort residents to their homes to get what they need for the short term, however, “they will not be able to stay.” Officials will meet with those residents at the West Trenton firehouse later today to give them further information.

About 55 homes were damaged in the explosion and resulting fire, about 20 of which “will be uninhabitable,” Steinmann said. Building inspectors are on the scene today, assessing the damage, he said.

He noted that some residents were escorted into their homes Tuesday night to retrieve pets. “We believe that all the pets are out,” he said.

A call center will provide information to residents and businesses who wish to make donations. That number is 609-538-7587.

Donations of clothing and blankets are welcome, but Steinmann said they must be new, with tags.

Cash and gift card donations are preferred, Steinmann said.

Steinmann thanked the various officials, including EMT, police and firefighters, and community members who responded. “I have never seen a community pull together as much as this community has over the last 24 hours,” he said.
